## Abstract

A content management device, includes: a folder level access control information storage unit configured to store folder level access control information indicating access rights of a user to a folder where content is stored; an access control unit configured to acquire content level access control information indicating access rights of a user to content, from a predetermined content level access control unit; and a user interface configured to output display data for displaying a hierarchical structure between at least one folder and at least one content stored in the at least one folder, along with information indicating whether or not an inconsistency has occurred in access rights between the folder level access control information of the at least one folder and the content level access control information of the content stored in the at least one folder.

## Claims

### Claim 1

A content management device, comprising:
a folder level access control information storage unit configured to store folder level access control information indicating access rights of a user to a folder where content is stored;
an access control unit configured to acquire content level access control information indicating access rights of a user to content, from a predetermined content level access control unit; and
a user interface configured to output display data for displaying a hierarchical structure between at least one folder and at least one content stored in the at least one folder, along with information indicating whether or not an inconsistency has occurred in access rights between the folder level access control information of the at least one folder and the content level access control information of the content stored in the at least one folder, wherein,
the user interface is configured to receive an operation for causing access rights of content for which an inconsistency has occurred in access rights to coincide with access rights of content which is stored in the same folder as the content and for which an inconsistency has not occurred in access rights, and
the access control unit is configured to output instructions, to the content level access control unit, for updating the content level access control information of the content for which an inconsistency has occurred in access rights such that the access rights of the content for which an inconsistency has occurred in access rights coincide with the access rights of the content for which an inconsistency has not occurred in access rights, in response to the operation.

### Claim 2 (depends on 1)

The content management device according to claim 1, wherein
the user interface is configured to output display data for displaying a folder for which an inconsistency has occurred in access rights, in a different display form from that of a folder for which an inconsistency in access rights has not occurred.

### Claim 3 (depends on 1)

The content management device according to claim 1, wherein
the user interface is configured to output display data for displaying content for which an inconsistency has occurred in access rights, in a different display form from that of content for which an inconsistency in access rights has not occurred.

### Claim 4 (depends on 1)

The content management device according to claim 1, wherein
the user interface is configured to receive an operation for causing access rights of content for which an inconsistency has occurred in access rights to coincide with access rights of a folder where the content is stored, and
the access control unit is configured to output instructions, to the content level access control unit, for updating the content level access control information such that the access rights of the content coincide with the access rights of the folder based on the access control information of the folder, in response to the operation.

### Claim 5 (depends on 1)

The content management device according to claim 1, wherein
when content is added to a folder, the user interface is configured to output display data for displaying a screen for selecting whether or not access rights of the content are caused to coincide with access rights of the folder, and
in the case the access rights of the content are selected to coincide with the access rights of the folder on the screen, the access control unit is configured to output instructions, to the content level access control unit, for storing content level access control information of the content such that the access rights of the content coincide with the access rights of the folder based on the access control information of the folder.

### Claim 6 (depends on 1)

The content management device according to claim 1, wherein
when receiving an operation for content for which an inconsistency has occurred in access rights, the user interface is configured to output display data for displaying that an inconsistency has occurred in access rights.

### Claim 7 (depends on 1)

The content management device according to claim 1, wherein
the content level access control unit is provided in a different device from the content management device.

### Claim 8

A content management method performed by a content management device, comprising the steps of:
acquiring folder level access control information indicating access rights of a user to a folder where content is stored, from a folder level access control information storage unit;
acquiring content level access control information indicating access rights of a user to content, from a content level access control unit;
outputting display data for displaying a hierarchical structure between at least one folder and at least one content stored in the at least one folder, along with information indicating whether or not an inconsistency has occurred in access rights between the folder level access control information of the at least one folder and the content level access control information of the content stored in the at least one folder;
receiving an operation for causing access rights of content for which an inconsistency has occurred in access rights to coincide with access rights of content which is stored in the same folder as the content and for which an inconsistency has not occurred in access rights; and
outputting instructions for updating the content level access control information of the content for which an inconsistency has occurred in access rights such that the access rights of the content for which an inconsistency has occurred in access rights coincide with the access rights of the content for which an inconsistency has not occurred in access rights, in response to the operation.

### Claim 9

A non-transitory computer-readable recording medium storing a program for causing a content management device to realize:
a function for storing folder level access control information indicating access rights of a user to a folder where content is stored;
a function for acquiring content level access control information indicating access rights of a user to content, from a prescribed content level access control unit;
a function for outputting display data for displaying a hierarchical structure between at least one folder and at least one content stored in the at least one folder, along with information indicating whether or not an inconsistency has occurred in access rights between the folder level access control information of the at least one folder and the content level access control information of the content stored in the at least one folder;
a function for receiving an operation for causing access rights of content for which an inconsistency has occurred in access rights to coincide with access rights of content which is stored in the same folder as the content and for which an inconsistency has not occurred in access rights; and
a function for outputting instructions for updating the content level access control information of the content for which an inconsistency has occurred in access rights such that the access rights of the content for which an inconsistency has occurred in access rights coincide with the access rights of the content for which an inconsistency has not occurred in access rights, in response to the operation.
